The average American will set their temperature anywhere from 68-75 degrees. In our opinion, 72 degrees is the perfect temperature to set your AC at. AC systems are designed to cool a home. Things like insulation also matter, but actually, most people don’t know that an average AC unit designed to cool a home is designed with an “about 20 degree” difference.

This means if it is 105 degrees outside, the AC system is designed to handle the stress of a 20-degree drop to 85 degrees. If it is 105 degrees outside and you set your AC to 65-70, you are putting undue stress on your system, which can cause it to malfunction, overheat, and not be able to meet the setting you set.
